Local car posted for sale, maybe I’m not as educated as I thought. But even with the fuel pressure regulator turned up that seems inflated.

Thoughts?

Kinda pushing it. Prob up near 100% and you can bump the fuel pressure to help, but you’d need a tune obviously.

I pushed just over 400 crank HP out of 19's with my KB, the stock block, and an FMU.

I ran that combo for about a year before swapping from SD to MAF and 42s. Admittedly, the 19's and FMU setup ran better driveability wise but during boost, injector pressure was high, high, high.

I was also running a 225L High pressure fuel pump and KB Boost-a-Pump (which became a voltage regulator after swapping to 42s).

You can push even more out of an injector N/A.

Is it outside of spec for an injector? Oh yeah. LOL Doable though.

NA setup can get away with making power on smaller injectors.

We didn't always have all these fancy computers and chips and programs and support "things" laying around when we wanted to make more power. What we had to do instead of tuning and swapping out EECs is tune everything mechanically.

One tried and true method for doing that was to jack fuel pressure through the roof. As pressure goes up, volume goes down, so we started putting larger fuel pumps into things....

Same concept though. Just jack the fuel pressure to Jesus, and tune it for that. However, you are not sucking that much air through a stock MAF anyway, so it's BS.

the add says its a 93 Cobra. Didn’t they have 70mm maf? I could see a standard 55mm having trouble supporting 400hp. But wouldn’t a 70mm do it?

I am going to go out on a limb here and say that based on the quality and understanding of the text the author put in their classified that this likely is not an original Cobra. This is more likely a 93' Mustang with a Cobra emblem.
